Amy's ass.

"Come over here, Amy. I'm gonna fuck your ass, too."

Amy squeals with delight, and bounces out from underneath Lisa. She starts to slide off the bed when you stop her. "No, baby. Lay on the bed with your ass in the air."

Amy does as told, and Lisa, still quivering from her massive orgasm, gets off the bed to make room. You hesitate for a moment, and say, "Wait, Amy. Do we need to lube up again?"

She nods her head, then commands you, "Stick your cock in Lisa's cunt, fuck her. Her cum should be enough." Gladly, you push Lisa back onto the bed, then bring her to the edge, plunging your dick deep into her pussy. Lisa moans with pleasure. You see her eyes roll back, and you realize she's cumming again. You feel your cock soaked with the juices of Lisa's cunt, and you make a few more thrusts to fully coat yourself.

You pull out and climb onto the bed and position yourself above Amy, your huge erection hovering over her firm ass. Her ass rises off the bed, and she turns back to face you. "Stop teasing, John. Fuck me!"

You grab Amy around the waist and guide your cock into her puckered asshole. As you enter, your cock makes a squishy sound, the result of Lisa's juices. Amy is still looking into your eyes, now biting her lip and breathing very heavily. You remember how you started with Lisa, who seemed to enjoy it, so you thrust heavily and pull Amy's ass deep onto your cock. Amy yells, "Ahhhh, fuck, yes!" and you know your attentiveness has paid off. You start to fuck Amy's ass, faster than you fucked Lisa's, knowing that Amy has done this many times before. Her ass is no less pleasurable, however, and you now find yourself inching closer to climax.

Lisa, finally recovered from the plowings she received, walks up next to the bed and grabs your head, kissing you hard as you continue to ram Amy's ass. As you make out with Lisa, her hand finds its way to Amy's tummy, then to Amy's cunt. She starts to massage Amy's pussy, then breaks the kiss and diverts her attention to finger-fucking Amy while you buttfuck her. Amy's howls of ecstasy get louder and louder, further increasing your arousal. Amy gushes juice onto Lisa's fingers, and you feel Amy's body convulse with orgasm.

This is enough to push you over the edge, and you say, "Girls, I'm gonna cum." With amazing agility, Amy slides off of your cock, flips over, and sits up, grabbing your cock and stroking it furiously. Lisa finds Amy's snatch again, and continues to finger her, now also kissing her perky tits.

"Cum on my tits, John. I want your manhood all over me." Almost immediately upon her finishing her sentence, you explode, firing a few large loads all over her tits and up to her neck. Lisa also positioned herself to take a couple of loads on her tits as well, and now kisses Amy, the two girls pressing their cum-covered tits against each other. Amy keeps stroking, urging every drop of cum out, and her hand is now covered in your jizz. Amy moves her head in and sucks hard on your cock as well as her fingers, and Lisa bends to lick your cum off of Amy's tits.

"You taste soooo good, John," Lisa says.

"Mmmm hmmm," Amy agrees, your cock still stuffed in her mouth. The humming of her response caused a pinch more cum to squirt out, and Amy's tongue found it quickly. The girls slip to the ground and you sit on the floor as well, the girls still groping your cock and licking each other.
